Mozilla Firefox uses . . . . . . . . engine.

The correct answer is Option D: Quantum.

Every web browser needs a special 'brain' to show you websites correctly. This 'brain' is called a rendering engine (or browser engine). Its job is to read the code of a webpage (like HTML, CSS, and JavaScript) and then draw everything on your screen exactly as it should look – text, images, videos, and interactive parts.

Mozilla Firefox, a popular web browser, uses an engine that was massively improved and relaunched under the name Quantum. While the underlying core engine is still called Gecko, the 'Quantum' project in 2017 brought huge changes and made Firefox much faster and more efficient. So, when people talk about the modern Firefox engine, they often refer to it as the 'Quantum engine' because of these significant improvements.

Let's look at why the other options are not correct:

Option A: Blink is the rendering engine used by browsers like Google Chrome, Opera, Microsoft Edge (the newer versions), and Brave.

Option B: Webkit is the rendering engine primarily used by Apple Safari and other browsers on Apple devices. The Blink engine (used by Chrome) was actually developed from Webkit!

Option C: Dlink is not a web rendering engine at all. It's a well-known company that makes computer networking equipment, like Wi-Fi routers.
